Standard Specification for Limestone for Dusting of Coal Mines
standard by ASTM International, 12/01/2013

Category:

Description

1.1 This specification covers limestone suitable for use as dust in coal mines to reduce risk of coal dust explosions.

Note 1–Limestone can serve as a source of incombustible material in coal mine operations. Limestone is dusted onto coal exposures in sufficient amount so that not less than 65 % of all loose dust shall be limestone incombustible material. In return air courses the concentration of incombustible materials should be not less than 80 % of the total dust (MSHA 30 CFR 75.403). With such a concentration of limestone incombustible material, dust explosions cannot initiate or be propagated from nearby gas explosions. The limestone must be substantially dry in order to dust satisfactorily.
